Lab-Grown Diamond Engagement Ring

Fingers extend gracefully beneath the elongated silhouette of a marquise diamond, its tapered points catching light like whispered promises. This three-stone semi-set engagement ring offers a poised foundation for an 8 x 4 mm marquise center, designed to amplify the stone’s dramatic, vintage-inspired allure.

Crafted in cool, enduring platinum, the mounting balances strength with refined elegance. Each prong is hand-finished to cradle the diamond securely while maintaining a low-profile setting that rests comfortably against the skin. The band’s subtle curvature and smooth polish invite daily wear, whether worn solo or paired with complementary bands.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond, ensuring clarity and brilliance without compromise to the earth.

This ring suits those who appreciate architectural lines and a statement that elongates the hand, ideal for slender fingers or anyone drawn to a bold yet wearable design. Its semi-set nature allows you to select a center stone that resonates personally, making the piece uniquely yours.

Resizing is available to ensure a perfect fit, and the studio’s Brooklyn artisans inspect each piece meticulously before it leaves our workshop.
